CPT® Code 23921

Disarticulation of the shoulder, also known as shoulder amputation, is a surgical procedure that involves the complete removal of the arm at the shoulder joint. This procedure is rarely performed and is typically reserved for patients with severe conditions such as extensive malignant tumors or significant traumatic injuries that compromise the viability of the arm. The procedure is complex and requires careful dissection of various muscles, nerves, and blood vessels to ensure that the amputation is performed safely and effectively. The official description for CPT® Code 23921 specifically refers to the secondary closure or scar revision that occurs at the site of a previous shoulder disarticulation. This may involve the removal of any necrotic or infected tissue and, if necessary, the excision of scar tissue to improve the appearance and function of the area. The closure of the amputation site may utilize skin grafts or flaps to promote healing and restore the integrity of the surrounding tissues.
